Staff called B.C. Poison Control, which advised the school to call BC Ambulance Service.

Parents of the students involved were called.

“Out of an abundance of caution, the five students were brought to hospital to be monitored and were released,” the statement said.

It added that the district “wants to assure families that student and staff safety and well-being is a top priority. The school conducts daily sweeps of school property for any trash, glass, and drug paraphernalia.”

R.C. Garnett school sent a letter to parents informing them of the incident.

School staff will be discussing the dangers of picking up unknown objects with students.

“The District is also encouraging families to continue these conversations at home,” the district release said.
